Basement Flood Cleanup & Restoration in Calgary
Water in your basement after a storm, a sewer backup or a burst pipe? DKI Calgary handles basement flood cleanup 24/7, with crews on site in under 90 minutes on most Calgary calls. Call 1-888-272-9543 and we take it from there.
What Happens When You Call About a Flooded Basement
Call our 24/7 line at 1-888-272-9543 and we ask a few quick questions: where the water is coming from, roughly how deep it is, and whether the basement still has power. A crew is dispatched right away and is on site in under 90 minutes on most Calgary calls. Basement floods are a core part of our water damage restoration in Calgary, and we have served Calgary since 1981.
On arrival, the crew checks for hazards such as live outlets, then stops the source if it can be stopped. Pumps and extraction wands pull standing water off the concrete and out of carpet and underlay. Moisture meters and thermal cameras then show how far water has wicked into walls and under flooring. We photograph the damage and log readings for your Xactimate estimate. The aim of that first visit is to leave no standing water and drying equipment running.
While you wait for the crew, a few safe steps help:
Stay out if water nears outlets or panel
Shut off the main water valve if safe
Stop running taps, toilets and laundry
Move dry valuables and documents upstairs
Photograph water levels and damaged items
Drying and Cleaning a Finished Basement: What Can Be Saved
What can be saved comes down to the type of water and how long materials stayed wet. After a clean-water leak from a supply line or hot water tank, carpet can sometimes be dried in place, although the underlay is often replaced. After a sewer backup, porous materials that touched the water come out, including carpet, underlay, drywall and insulation. Our guide to what to throw out vs save after a basement flood goes item by item.
Drywall is usually cut a set height above the wet line instead of being removed floor to ceiling, which keeps the rebuild smaller. Laminate and vinyl plank trap water underneath and often have to be lifted. Opened wall cavities are dried with air movers and dehumidifiers, and readings are logged until materials meet a dry standard. Furniture, photos, electronics and boxed items can go to our contents restoration team to be assessed and cleaned.
How common finished-basement materials usually fare:
Carpet: sometimes dried after clean-water leaks
Underlay: often replaced, even after clean water
Drywall: cut and replaced above the wet line
Insulation: removed once it is soaked
Sewer-soaked porous materials: removed and disposed of

Calgary-Specific Causes of Basement Flooding
Sewer backup is the most serious flood we clean up, because it is Category 3 water carrying sewage and bacteria. The City of Calgary notes that aging sewer infrastructure in older communities is vulnerable to tree roots and backups, and during heavy rain, overloaded storm drains can push water back into basements. A backwater valve helps, but only if the flapper moves freely and the valve is kept clear. Learn how IICRC water damage categories change the cleanup.
Spring brings a different set of problems. Melting snow pools against foundations, window wells fill and overflow, and small foundation cracks start to seep. The City puts the highest river flood risk between May 15 and July 15, when mountain rain meets melting snowpack and the Bow and Elbow rise. Groundwater can climb in nearby communities, and a sump pump that fails or loses power during a storm leaves water nowhere to go. Our basement flooding prevention guide covers the fixes.
Winter floods usually start inside the house. Pipes in exterior walls can freeze and split during a cold snap, and the leak often appears only once they thaw. Hot water tanks in basement utility rooms can fail with little warning and soak the carpet and drywall around them. In a finished basement or secondary suite, water travels under flooring and into the next room before anyone notices. Our frozen and burst pipe guide explains what to shut off first.
Sources we look for in Calgary basements:
Sanitary sewer backup during heavy rain or from a blocked line
Sump pump failure or power loss in a storm
Backwater valve stuck, missing or clogged with debris
Snowmelt and overland water through window wells and cracks
Burst pipes and leaking hot water tanks in winter
Our Basement Flood Restoration Process, From First Visit to Rebuild
Every basement flood follows the same broad path: remove the water, take out what can’t be saved, clean, dry and rebuild. How long each stage takes depends on the water category, the size of the affected area and how quickly drying starts. Here is how a typical job runs with DKI Calgary, with one company handling every stage.
What to expect, step by step:
First visit: safety check, water extraction, photos and moisture mapping
Tear-out: removing wet underlay, drywall and insulation that can't be saved
Cleaning: antimicrobial treatment, with full decontamination after a sewer backup
Drying: air movers and dehumidifiers, typically 3 to 5 days
Rebuild: drywall, paint, flooring and trim restored by our own crews
Through every stage we work directly with your insurer and adjuster. Once drying is confirmed, our in-house rebuild team takes over, so there is no hand-off to another contractor. As Erin P wrote in a Google review, “Thanks to the entire team for the exceptional customer service and for putting our basement back together!”
Related Services & Guides
A basement flood often brings other problems with it. Drywall that stays wet can grow mould, and sewage cleanup falls under biohazard work. In older homes, drywall joint compound, vinyl flooring or vermiculite may contain asbestos, so materials should be tested before tear-out. We do our own asbestos sampling and abatement, and the links below cover the rest.
Frequently Asked Questions – Basement Flood Cleanup in Calgary
Who should I call when my basement floods in Calgary?
Call a restoration company that can extract water, dry the structure and rebuild. DKI Calgary answers 24/7 at 1-888-272-9543 and is on site in under 90 minutes on most Calgary calls. For Airdrie, Chestermere and other nearby towns, crews travel out on the same 24/7 basis. Insurers generally expect you to limit further damage, so you do not need to wait for an adjuster. You can also report a claim online.
How much does basement flood cleanup cost in Calgary?
Cost depends on the water category, how much of the basement is affected and how much has to be rebuilt. As a reference point, our sewer backup guide puts sewer backup cleanup at typically $2,500 to $12,000+. That is a typical range, not a quote. Every job is priced after an inspection, and if your claim is accepted, your insurer generally pays the covered work less your deductible.
Will my home insurance cover a flooded basement?
It depends on your policy and where the water came from. Sudden leaks such as a burst pipe are often covered. Sewer backup usually needs a sewer backup endorsement, and rain or snowmelt entering from outside often needs overland water coverage. Groundwater seepage may be excluded. Our overland water insurance guide explains the difference. We work directly with adjusters and provide photos, moisture readings and an Xactimate estimate.
How long does it take to dry out a flooded basement?
Structural drying typically takes 3 to 5 days once standing water is out, but every basement is different. Concrete, thick carpet and closed wall cavities hold water longer, and sewer backups add time for tear-out and decontamination. We take moisture readings throughout and shut equipment off only when materials are dry. Rebuilding comes after that. Read how long water damage takes to dry for more detail.
How soon can mold grow after a basement flood?
Mold can start growing on wet drywall, carpet and wood within 24 to 48 hours, and Health Canada guidance says to act within 48 hours. Basements tend to be cool and damp, and growth often starts behind walls or under flooring where you cannot see it. Fast extraction and drying is the best prevention. If mold has already appeared, our IICRC-certified mold remediation team can remove it safely.
Can I stay in my home or clean up the basement myself?
In many cases you can stay upstairs while we work, as long as the power is safe and the water was clean. Sewer backup is different. Category 3 water carries bacteria, so keep children and pets away and leave the cleanup to crews with protective gear. If a little clean water reached bare concrete, a wet vac and fans may be enough. Once carpet, drywall or insulation is soaked, professional drying helps prevent hidden moisture and mould.
